4 housing hinge is set, therefore oscillating rod 401 can drive the earthing wheel 402 of trench digging bar bottom and straight knife to open in rotation process
Ditch device 403 is swung.The seeding monomer is carried out using fertilising is synchronous with sowing, and earthing is carried out after ditching-fertilizing.The device is real
Show that trench digging is earthing integrated, straight knife plough can reduce the size of whole device, and disk earthing is passive earthing, is being worked
Disk, which rolls, in the process reduces resistance.
It lifts up formula hack press wheel 5 to connect by lever construction with front-wheel 7, lifts up the central shaft of formula hack press wheel 5 and front-wheel 7
It is hinged with the both ends of lever respectively.Front-wheel 7 is plastic roller, and it is hollow mesh wheel that clear soil, which stirs wheel 5, lifts up formula hack press wheel 5 with before
It can be interfered between wheel 7, it can be toward upwarping when front-wheel 7 meets soil block, clear soil stirs 5 pairs of front-wheels 7 of wheel and generates pressure, ensures front-wheel 7
Soil block can be crushed；Equally when clear soil, which stirs wheel 5, encounters barrier tilting, front-wheel 7 can crush soil block under leverage, nothing
Spring need to be used.
As shown in fig. 6, lifting up formula hack press wheel 5 including hollow type grid wheel 501 and in hollow type grid wheel 501
Clear soil flabellum 502, hollow type grid wheel 501 is cylinder, and outer surface is hollow type grid, can be realized by rolling chopping
To the effect that ravels of large clod, and then realize the whole soil of grading and secondary suppression effect.Hollow type grid wheel 501 is fixedly arranged in the middle of
Central shaft, clear soil flabellum 502 are fixed on center shaft.As shown in fig. 7, clear soil flabellum 502 includes multiple blades, blade edge surrounds
Central shaft uniform intervals are arranged, and blade is oblique, and the present embodiment includes three blades.502 plate of clear soil flabellum, which will enter, to be engraved
Soil inside abortive haul lattice wheel 501 is excluded from the both sides of hollow grid wheel, can be ensured kind of the soil amount taken in this way, be realized wheel
Secondary suppression.Formula hack press wheel 5 is lifted up during advance, some bigger hack soil blocks can enter through hollow grid to be engraved
On clear native flabellum 502 inside empty formula grid wheel 501, since clear native flabellum 502 is oblique, hack soil block can be from clear soil
The both sides of flabellum 502 are cleared up away, and the effect of hack, whole soil, grading is realized.Press wheel 6 is connect by spring with rack 1,
To realize be uneven up and down motion of the press wheel 6 with ground, play the role of suppressing soil.
Embodiment 2
As different from Example 1, its in this implementation is adjustable scrapes kind of a mode difference.As shown in Figure 10, it is set in feed mechanism for seed 3
There is an adjustable seeds scraper, the center axis connection of one end and 3 right shell body of feed mechanism for seed of adjustable seeds scraper, the other end is from right shell body top
It is stretched out in the observation panel 302 in portion, i.e., people can be adjusted kind of an angle of scraping for adjustable seeds scraper from outside.It is adjustable to scrape kind
Plate includes plate I 312 and plate II 320, at an angle between plate I 312 and plate II 320, and plate I 312 and plate II 320 are in one
Formula structure.The center axis connection of plate I 312 and left shell, sets that there are three gears on plate II 320, is gear IV 315, gear respectively
V 317 and gear VI 319, gear V 317 between gear IV 315 and gear VI 319, gear V 317 respectively with gear IV
315 and gear VI 319 engage.It is respectively fixed on gear IV 315, gear V 317 and gear VI 319 and scrapes kind of roller I 314, scrapes
It plants roller II 316 and scrapes kind of idler wheel III 318.As shown in figure 11, each gear and the distance for scraping kind of idler wheel to central shaft are fixed
, in the rotation process of adjustable seeds scraper, the relative position scraped between kind of idler wheel and the suction kind mouth of seeds sucker 311 becomes
Change so that scrape kind of idler wheel and change with the distance between kind of mouth is inhaled：When adjustable seeds scraper is located at the position of bottom, scrape
It plants idler wheel and inhales maximum at a distance from before planting mouth；When adjustable seeds scraper turns to the position of the top, scrapes kind of idler wheel and inhale
The distance between kind mouth minimum.Therefore the width by channel of seed can be controlled by changing angle according to seed size
Degree.After adjusting to suitable width, blown off by scraping the extra seed that kind of pair of rollers is adsorbed at kind of mouth.
Other are the same as embodiment 1.
